Lewis has been sidelined since tearing his right triceps on Oct. 14 against the Dallas Cowboys. The 17-year NFL veteran was eligible to come off the injured reserve-designated to return list on Sunday, but the Ravens did not move him to the active roster before Saturday's deadline.

The 37-year-old Lewis has been practicing for the past two weeks but obviously is not healthy enough to return.

His absence means the Ravens will be short at middle linebacker on Sunday. Jameel McClain is out with a neck injury and the status of Dannell Ellerbe (sprained ankle) is uncertain.

Baltimore hopes to have outside linebacker Terrell Suggs, who missed last week's game against Washington with a torn right biceps.
